FAN AND LIMIT CONTROLS (See FIG. 2 or FIG. 3 for Control Locations)
Settings : Fan Off - 95F , Fan On - 130F , High Limit - 200F
NOTE: For constant fan operation , push the MANUAL-AUTO switch to MAN POSITION (If Equipped).
CAUTION: The flue products may contain carbon monoxide, particularly when the wood fire is being starved for
air (made to burn at a slow rate), therefore, the flue pipe must seal tight.
COMBUSTION AIR: where fans are used in the fuel storage area, they should be installed so as not to create
negative pressures in the room where the solid fuel burning appliance is located.
OUTSIDE COMBUSTION AIR : Provision for outside combustion air may be necessary to ensure that fuel-
burning appliances do not discharge products of combustion into the house. Guidelines to determine the need
for additional combustion air may not be adequate for every situation. If in doubt, it is advisable to provide
additional air. Outside combustion air may be required if:
1. The solid fuel-fired appliance does not draw steadily, experiences smoke roll-out, burns poorly or back-
drafts whether or not there is combustion present;
2. Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances, smell, do not
operate properly, suffer smoke roll-out when operated or back-draft whether or not there is combustion
present;
3. Any of the above are alleviated by opening a window slightly on a calm (windless) day;
4. The house is equipped with a well-sealed barrier and tight fitting windows and/or has any powered
devices, which exhaust house air.
5. There is excessive condensation on windows in the winter; or
6. A ventilation system is installed in the house.
If these or other indications that infiltration air is inadequate, additional combustion air should be provided from
outdoors.
DUCT INSTALLATION:
1. Locate the furnace as centrally as possible in the home so the best warm air distribution may be
enjoyed.
2. Use an extended plenum (central duct) at least one size larger than called for in National Warm Air
Standards.
3. Use a minimum pipe size of six inches diameter in runs and in no case smaller than 5 inches in
diameter.
4. Slope extended plenums and runs as much as possible to facilitate gravity flow of warm air.
IMPORTANT: This furnace must have a Minimum return air duct size equal to 250 sq. in. and a Minimum
supply air duct size equal to 180 sq. in. The supply air extended plenum should extend 8 – 10 feet out from the
furnace and then gradually transitioned to the end of the duct system to provide a .20” W.C static pressure.
